Step-by-step explanation:
Slope=9
i)
When line is parallel
y+5=9(x-6)
y+5 = 9x - 54
<h3>59 = 9x-y </h3>When line is perpendicular
y+5=-1/9(x-6)
9(y+5)= -1(x-6)
9y + 45 = -x+6
<h3>x+9y = -39</h3><h2>MARK ME AS BRAINLIST </h2>Answer: 31.43 cm
Step-by-step explanation:
The length of an arc is calculated using the formula:
X 2
r
where : theta is the angle in degree
r = radius
If the angle is given in Radian , the length can be calculated using the formula:
L = r∅
Since , the angle is given in degree , we will use the first formula.
L = X 2
r
L = X 2 X π X 15
L = X 2 X
X 15
L =
L = 31.42857143
L ≈ 31.43 cm
